Benefits of technology

[0006]The present invention provides user interface systems comprising a touch screen actuator and a tactile key, in which the tactile key is placed adjacent to the touch screen actuator so that manipulation of the tactile key can be detected by the to

Problems solved by technology

One major disadvantage of such hardware systems, however, is that the keyboard layouts are either permanent, or are cumbersome and expensive to reconfigure.
Hence, these systems generally are standardized and not tailored to individual users.
Where accuracy is critical, operation of a touch screen by direct manipulation can generate an unacceptable risk of errors.
Hence, the accuracy with which a user touches a location with the requisite contact pressure required to actuate one selected graphic object out of many displayed on the same touch screen cannot be controlled

Embodiment Construction

[0035]According to one aspect of the present invention, a software upgrade kit and one or more key modules can be readily utilized to add additional key capacity to an existing point of sale (POS) or other terminal having a touch screen user interface, such as an NCR DynaKey™ POS device. Further details of such systems are found, for example, in U.S. Pat. No. 6,002,395 and 5,920,312 which are incorporated by reference herein in their entirety. See also U.S. Pat. No. 6,411,286 which is also incorporated by reference herein in its entirety. While the present invention is described in the context of such terminals, it will be recognized that the present teachings can be adapted to various touch screen based terminals to provide a high degree of design and user flexibility in a cost effective manner, as addressed in greater detail below.

[0036]FIGS. 1-4 show exemplary embodiments of a touch screen user interface system which may be suitably modified to implement the present invention as ...

Abstract

User interface systems comprising a touch screen actuator and a tactile key, in which the tactile key is placed adjacent to the touch screen actuator so that manipulation of the tactile key can be detected by the touch screen actuator. Tactile key modules that can be so placed adjacent to a touch screen actuator, and methods of producing such user interface systems, as well as, repositioning such tactile key modules, are also described.

Description

FIELD OF THE INVENTION[0001]The present invention relates to improvements in the field of touch screen user interface systems. In particular, the present invention relates to reconfigurable touch screen systems augmented by dynamic or static tactile keys that provide signaling action, detectable by touch screen actuators, with improved accuracy and ease of use.BACKGROUND OF THE INVENTION[0002]Traditional user interface hardware systems such as tactile keyboards typically are actuated by applying pressure to a selected key, which then causes the actuation of further components within the keypad or keyboard. The key to which such pressure is applied generally is a discrete hardware element, and the key can readily be designed to require the application of a pressure exceeding a threshold level for its actuation. As a result, the discrete hardware keys in such systems foster accurate data entry at high speeds. One major disadvantage of such hardware systems, however, is that the keyboa...
